Epson printers are generally easy to install, you
just remove your existing cartridges and drop the ciss cartridge set
in position. Ensure that the ribbon tubes run freely and that is
Canon however have included some trickery that
needs to be overcome.
The ribbon tube feeding the cartridges from
the ink tanks will not allow the cover to be closed properly. Canon
has a cover open switch which can be easily disable with a roll of
paper or presstick. They have figured you will easily get past this
an so it appears they have installed a light sensor in the printer.
When this is activated it won't allow the cartridges to be
recognized. This applies only when a new cartridge is installed. To
bypass this check the light must be shut out on the first pass of
the new install. Once it is happy no further rejections will occur.
Canon printers have a cover open switch that
needs to be disabled. When the cover is open it gives a 6502 error.
That is easily overcome .
